Saudi Arabia will be home to the world's largest hotel come 2017. The Abraj Kudai hotel will reportedly have 10,000 rooms and suites in 686,000 square feet of space, and will cost $3.5 billion to build. That puts it well past the current titleholder, the Venetian Las Vegas. The Abraj Kudai will be conveniently located around the corner from the Masjid al-Haram, the world's largest mosque, and will cater to wealthy Muslims who come to Mecca on pilgrimage. Among the posh amenities planned for the mega-hotel are 70 restaurants, a mall, a convention center, prayer areas, and even five entire floors reserved for members of the Saudi royal family.

According to renderings provided by Dar Al-Handasah, the design firm handling the Abraj Kudai, the hotel will have 12 towers; ten of them will have four-star rooms, while the other two feature five-star rooms. The interiors will be designed by the London-based Areen Hospitality Group. There are no estimated room rates yet, but expect them to be on the higher end, especially since each of those 12 towers will have a helipad on top for guests who arrive via chopper.
